Let $L / K$ be a finite field extension.
Finite Galois Extension
$L / K$ is a (finite) Galois extension if and only if the fixed field of its automorphism group is $K$:
- $\map {\operatorname{Fix}_L} {\Gal {L / K} } = K$
Arbitrary Galois Extension
$L / K$ is a Galois extension if and only if it is normal and separable.
